Predecessor of "The Cosmos Co. Eng." (see). Before WWI, Brazil-Straker built cars of a remarkable quality.

-Around 1915, by order of the British government, they had to manufacture aircraft engines such as the Curtiss and other  Rolls-Royce engines, as well as "Eagle" parts and spare parts.

-From R-R they made the 75 hp "Hawk", as well as the R-R "Falcon" I series with 190 hp. They also built the 80 hp Renault.

From appendix 9: We obtained a diagram of the initial 14-cylinder Mercury. This was the one that Roy J. Fedden made together with J. Bettler while they were in this company. Later in Cosmos there was a new Mercury that had nine cylinders in a single row.

-It stands out that the cylinders were not in the same radial plane but were displaced helically due to connecting rod fittings to the crankshaft, which can be seen in the diagram below.

-It seems that Brazil-Straker's initial plans were acquired by a certain Sir George White, along with the rights, 7 physical engines, resources and Fedden's collaboration.

"Diagram explaining the rod connections"

"All the connecting rods at the same collar"

-As the rods are connected to the crankshaft one beside another, they are displaced relative to the cylinder "disk", one rod remaining behind the next one, so forming a helicoid. The same thing happens to the other row.
